So, this patch just hooks the optimization also into store-merging so that the original testcase from the PR can be fixed. 2021-01-05 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/96239 * gimple-ssa-store-merging.c (maybe_optimize_vector_constructor): New function. (get_status_for_store_merging): Don't return BB_INVALID for blocks with potential bswap optimizable CONSTRUCTORs. (pass_store_merging::execute): Optimize vector CONSTRUCTORs with bswap if possible. * gcc.dg/tree-ssa/pr96239.c: New test.
